A ahmedragia21 Member Apr 27, 2009 #1 Hi, i wanna do a random PWM for an LED but using the cheapest thing maybe a pic16F48 , but i'd like to know other methods for not using a uC that can be used ?

A arunb Member Apr 28, 2009 #2 a 555 can be used...google for 555 applications, there are many out there...
A ahmedragia21 Member Apr 28, 2009 #4 I just wanna do a Random sequence for LED with Different duty cycles -_-
Sceadwian Banned Apr 28, 2009 #5 You're not going to get random out of a 555, a micro controller can easily generate pseudo random numbers. Linear feedback shift register - Wikipedia, the free encyclopedia

S solis365 New Member Apr 28, 2009 #7 why random pwm? you just want it to flash with a random on/off time?
A ahmedragia21 Member Apr 28, 2009 #8 no , i just wanna make 3 two LEDs that light by random sequences and at the same time the intensity of it get changed
